Interface for IFbeam

[sindhu-ku]

• Added new class for IFbeam interface in src/beam
• Can get POT info directly from IFBeam
• Have to also query other devices to get other beam info like horn current, position, etc.,

The overall approach here looks sound to me. I've made some comments inline about the strategy for when the IFBeam lookup fails and about the coding style---once we resolve those, we'll be good to go.

Ok I think I have included all of your suggestions. Just need a smarter way to recognize a data file instead of using Params

I wonder if you've been waiting for me? I think we should go ahead with what we have here for now, and continue to look for a way to determine whether a file is data in the future
